SECTION 4: First aid measures
4.1.
Description of first aid measures
First-aid measures general
: If exposed or concerned, get medical attention/advice. Show this safety data sheet to the
doctor in attendance. Wash contaminated clothing before re-use. Never give anything to an
unconscious person.
First-aid measures after inhalation
: IF INHALED: Remove to fresh air and keep at rest in a position comfortable for breathing. Get
medical attention if breathing is affected. If breathing is difficult, supply oxygen.
First-aid measures after skin contact
: IF ON SKIN (or clothing): Remove affected clothing and wash all exposed skin with water for at
least 15 minutes. If irritation develops or persists, get medical attention.
First-aid measures after eye contact
: IF IN EYES: Immediately flush with plenty of water for at least 15 minutes. Remove contact
lenses if present and easy to do so. Continue rinsing.
First-aid measures after ingestion
: IF SWALLOWED: rinse mouth thoroughly. Do not induce vomiting without advice from poison
control center or medical professional. Get medical attention if you feel unwell.
4.2.
Most important symptoms and effects, both acute and delayed
Symptoms/injuries
: Not expected to present a significant hazard under anticipated conditions of normal use.
Symptoms/injuries after inhalation

Special hazards arising from the substance or mixture
Fire hazard
: Extremely flammable gas.
Explosion hazard
: Heating may cause an explosion.
Reactivity
: Contains gas under pressure; may explode if heated.
5.3.
Advice for firefighters
Precautionary measures fire
: Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No
smoking.
Firefighting instructions
: Use water spray or fog for cooling exposed containers. Water spray may be useful in
minimizing or dispersing vapors and to protect personnel. Exercise caution when fighting any
chemical fire. Do not dispose of fire-fighting water in the environment.
Protection during firefighting
: Do not enter fire area without proper protective equipment, including respiratory protection.
Self-contained breathing apparatus.
Other information
: Do not allow run-off from fire fighting to enter drains or water courses - may cause explosion
hazard in drains and may reignite. Vapors may travel long distances along ground before
igniting/flashing back to vapor source. Vapors may form flammable and explosive mixture with
air.
SECTION 6: Accidental release measures
6.1.
Personal precautions, protective equipment and emergency procedures
General measures
6.1.1.
: Evacuate area. Eliminate every possible source of ignition. Ventilate area. Keep upwind. Spill
should be handled by trained clean-up crews properly equipped with respiratory equipment and
full chemical protective gear (see Section 8).
For non-emergency personnel
Protective equipment
: Wear Protective equipment as described in Section 8.
Emergency procedures
: Evacuate unnecessary personnel.
6.1.2.
For emergency responders
Protective equipment
6.2.
: Wear suitable protective clothing, gloves and eye or face protection. Approved supplied-air
respirator, in case of emergency.
Environmental precautions
Prevent entry to sewers and public waters. Notify authorities if liquid enters sewers or public waters. Avoid release to the environment.
6.3.
Methods and material for containment and cleaning up
For containment
04/30/2015
: Stop leak if safe to do so. Vapors may be suppressed by water fog.

Prepared according to Federal Register / Vol. 77, No. 58 / Monday, March 26, 2012 / Rules and Regulations
Methods for cleaning up
6.4.
: Eliminate ignition sources. Use explosion-proof equipment. Beware of accumulation of gas in
low areas or contained areas, where explosive concentrations may occur. Ventilate area. This
material and its container must be disposed of in a safe way, and as per local legislation.
Reference to other sections
See Sections 8 and 13.
SECTION 7: Handling and storage
7.1.
Precautions for safe handling
Precautions for safe handling
: Do not handle until all safety precautions have been read and understood. Do not get in eyes,
on skin, or on clothing. Cold burns may occur during filling operations. Containers and delivery
lines may become cold enough to present cold burn hazard. Use appropriate personal
protection equipment (PPE). Immediately rinse contaminated clothing thoroughly with water.
Gas can accumulate in confined spaces and limit oxygen available for breathing.Use only in
well-ventilated areas. Avoid breathing gas, vapors, mist. Keep away from heat, hot surfaces,
sparks, open flames and other ignition sources. No smoking. Take precautionary measures
against static discharge. Use explosion-proof equipment. Can form explosive mixtures with air.
Wash hands and other exposed areas with mild soap and water before eating, drinking or
smoking and when leaving work.
Naturally Occurring Radioactive Materials (NORM)
This product may contain detectable quantities of Naturally Occurring Radioactive Materials
(NORM) above background levels. This NORM material consists of small amounts of radon, a
naturally occurring radioactive gas; and the solid decay products of radon, called radon
daughters. Transport vessels should be assessed for gamma radiation; access around the
equipment may need to be restricted in accordance with OSHA 29 CFR 1910.96. For vessel
entry, this equipment should be assumed to be internally contaminated with long half-life decay
products that emit beta and alpha radiation, which is a radiation hazard if inhaled or ingested.
7.2.
Conditions for safe storage, including any incompatibilities
Technical measures
: Containers, even those that have been emptied, can contain explosive vapors. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame,
sparks, or other sources of ignition.
Storage conditions
: Keep only in the original container in a cool, well ventilated place away from : Direct sunlight,
Incompatible materials, Food. Keep the container tightly closed. Avoid temperature extremes.
Keep away from ignition sources. Containers which are opened should be properly resealed
and kept upright to prevent leakage. Do not store in unlabeled containers.
